J. PREOPERATIONAL TESTS

ALL dryers are thoroughly tested and inspected before leaving the factory. However, a preoperational test should be performed before the dryer is publicly used. It is possible that adjustments have changed in transit or due to marginal location (installation) conditions.

1.Turn on electric power to the dryer.

2.Refer to the Operating Instructions for starting your particular model dryer.

3.GAS MODELS ONLY

a.When a gas dryer is first started (during initial start-up), it has a tendency not to ignite on the first ignition attempt. This is because the gas supply piping is filled with air, so it may take a few minutes for the air to be purged from the lines.

NOTE: During the purging period, check to be sure that ALL gas shut-off valves are open.

NOTE: Gas model dryers are equipped with a Hot Surface Ignition (HSI) system which has internal diagnostics. If ignition is not established after one (1) time, the heat circuit in the HSI module will attempt two more ignitions (total of three ignition attempts). If there is no flame after the third ignition attempt the HSI module will lock out until it is manually reset. To reset the HSI (Hot Surface Ignition) system, open and close the main door and restart the dryer.

b.A gas pressure test should be taken at the gas valve pressure tap of each dryer to assure that the water column (W.C.) pressure is correct and consistent.

NOTE: Water column (W.C.) pressure requirements (measured at the pressure tap of the gas valve body):

Natural Gas -----------------

3.5 Inches Water Column (8.7 mbar)

Liquid Propane (L.P.) Gas ---

10.5 Inches Water Column (26.2 mbar)

IMPORTANT: There is no regulator provided in an L.P. dryer. The water column pressure must be regulated at the source (L.P. tank), or an external regulator must be added to each dryer.

4.Make a complete operational check of ALL safety related circuits:

a.Door Switch(es)

b.Hi-Limit thermostats

c.Cycling thermostat

d.GAS and ELECTRIC MODELS ONLY - Sail Switch

NOTE: The sail switch can be checked for proper operation by opening the lint drawer. While Pushing the lint drawer switch in, start a drying cycle. The heating unit should not activate (wait 30 sec.) If heat does activate, make necessary adjustments to the sail switch.
